Well, after getting bitten once by some python crash upon running setup-kolab 
(which apparently was due to some LDAP leftovers) I come to believe that the 
complete procedure should look like this:

1. apt-get remove --purge kolab kolab-syncroton
2. apt-get autoremove --purge
3. Remove databases:
    a. mysql -u root -p -e "drop database kolab;"
    b. mysql -u root -p -e "drop database roundcube;"
4. Remove IMAP spool files: rm -rf /var/lib/imap/ /var/spool/imap/
5. Remove LDAP files: 
rm -rf /etc/dirsrv/slapd-HOST/ /var/lib/dirsrv/slapd-HOST/
6. apt-get install kolab
7. Re-run setup-kolab

Note of caution: In my case, "apt-get autoremove --purge" failed with an error 
when removing cyrus-imapd: https://issues.kolab.org/show_bug.cgi?id=1481
I got round that by messing with /var/lib/dpkg/info/cyrus-imapd.postrm and 
replacing the line
db_get cyrus-imapd/removespools
with
db_get cyrus-imapd/removespools || true
but I'd be fairly surprised if that was the proper solution and not just an 
ugly hack... (...so be warned).

On first glance, though, I now have a running, pristine server again. If I run 
into any undesired side effects I'll make sure to post them here.

Cheerio,

Thomas
